Gone Home

On 7 June 1995, 21-year-old Katie Greenbriar (voiced by Sarah Elmaleh) returns home from overseas to her family's new home in fictional Boon County, Oregon. Her family consists of her father, Terry, a failed writer who makes a living reviewing home electronics; her mother, Janice, a wildlife conservationist who recently got promoted to director; and her 17-year-old sister Samantha (voiced by Sarah Grayson). Upon arriving, she finds the house deserted, much of their possessions still in moving boxes, and a note on the door from Sam imploring Katie not to investigate what happened.
Searching the house, Katie begins to piece together what happened during her absence. After moving in, Samantha found it difficult to adjust to her new high school, but eventually made friends with another girl, Yolanda "Lonnie" DeSoto, a JROTC cadet. The two bonded over Street Fighter, punk rock, grunge and the burgeoning riot grrrl movement, and after sneaking off to a concert, the two became romantically involved. After various incidents at school, Sam's parents found out about her relationship, forbade Sam to close her bedroom door while Lonnie was over, and went into denial that their daughter is a lesbian. As Lonnie was set to eventually ship out to begin her service, Sam was left distraught.
Two days after her farewell show, which coincides with the day of Katie's homecoming, and the week of Sam's parents going on a vacation (which is revealed to actually be a counseling trip instead of a camping trip, as they told others), Lonnie departed to her station, but eventually called Sam from a payphone to tell her that she got off the bus in Salem and she wanted them to be together. Sam's final journal entry to Katie explains that she packed up her things and took her car to find Lonnie, hoping to start a new life with her outside of Oregon. But she promises that she will one day see her again.
Optionally, Katie can find various other clues that provide information on additional events that happened during the time: it is implied that Janice was beginning to have romantic feelings towards a subordinate, and that Terry was berated by his father via letter about his failed writing work, as well as Sam and Lonnie's suspicion that the house was haunted by the deceased Oscar Masan, Terry's uncle and former owner of the house. It is also implied that Terry's decision to write about a character traveling back in time to 1963 to stop the Kennedy assassination may have been influenced by his own sexual abuse by Masan, which either occurred or ended in 1963, when he was 13 years old.
